llldl'lh@ STORAGE-BATTERY PLATE.

Applica-tion ined January G. 1923.

To all whom. t may concern.'

Be it known that l, JOHN BARNA, a citizen of the United States, residingat New London, in the county of New London and State oiI Connecticut,have invented new and useful Improvements in Storage-Battery Plates, ol1which the following is a specification. rlhis invention relates toimprovements in batteries, the general object el: the invention being toprovide a grid plate which will have greater strength than the plates asnow made and which can be manufactured to sell at low cost.

Another object ot the invention is to provide means to prevent the heat'from warping the plate when the battery is being charged or discharged.

rlhis invention also consists in certain other 'features oi constructionand in the combina-tion and arrangement ot the several parts, to beherein after tully described, illustrated in the accompanying drawingsand specilically pointed out in tie appended claims.

ln describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a side view of the improved plate.

Fig. 2 is a top edge View.

Fig. 3 is a side edge view.

Fig'. 4 is a section on line 4 4 of Fig. l.

Fig. 5 is a section on line 5-5 of Fig. l.

Fig. 6 is a section on line 6 6 ot Fig. l.

Fig. 7 is an enlarged view of one corner of the plate.

ln these views l indicates the trame of the plate7 2 the horizontal barsand 3 the vertical bars. As shown, the bars 2 are staggered with theirinner edges extending to the center of the trame and these edges arerounded as shown at 2. 3 taper from their centers towards their edges sothat these bars are of substantially diamond shape in cross section. Theinner edges of 'the trame are of similar shape. The plate is formed witha circular rib The vertical bars Serial No. 611,190.

at its center which is of the same cross sectional shape as the bars 3and inclined ribs 5 are arranged in the circle. The terminal lug 6 isstepped, as at 7, tor receiving a lead strip.

From the foregoing it will be seen that a grid plate is produced whichhas great strength yet ene which can be cheaply manufactured. rllhestaggered horizontal ribs or bars provide ample space for the activematerial and the peculiar form of these gives them great strength andenables the plate to stand charging and discharging to iitty ampereswithout warping. The circular rib and its bracing ribs will take up theheat in the plate and will prevent warping and pulling in from thecorners when the battery is being charged or discharged in excess otthirty ainperes.

lt .is thought from the foregoing description that the advantages andnovel features ot' my invention will be readily apparent.

l desire it to be understood that l may make changes in the constructionand in the combination and arrangement ot the several parts, providedthat such changes tall within the scope ot the appended claims.

lllhat l claim is:

l. A. grid plate for a battery comprising a trame, vertical andhorizontalribs therein and a circular rib at the center of the plate.

2. A grid plate for a battery comprising a trame, vertical andhorizontal ribs therein and a circular rib at the center ot the plateand inclined bracing means in the circular rib.

3. A grid plate for a battery comprising a trame, horizontal ribs ofhalt the thickness of the 'frame with their inner edges in alibi ment,the ribs on one side being alternately arranged witl'i respect to theribs on the other side and the inner edges of said ribs being rounded,vertical ribs, a circular rib in the middle of the plate, inclinedbracing ribs in the circular rib and a stepped terminal `tor the plate.

JOHN BAENA.
